The Department of Public Health England has created a very useful interactive radon map where you can see specific concentrations in each area of the UK . Take a look at the map here
As of 2010 , the UK ' s Health Protection Agency set 100 Bq / m3 as a target level “ because research published since 1990 has given scientists a greater understanding of the risks to our health of exposure to radon below 200 Bq / m3 ”.
Actions are recommended for levels above of 200 Bq / m3 . You can find a pricing list to know the costs of active mitigation methods , should your levels be too high . You can consult them here . Hopefully , your radon levels will be within the recommended values . Don ’ t forget to keep ventilating and , once again , thank you for purchasing an Airthings detector . About us Blog Careers
